What is 3404.0047.11 Fuse?

3404.0047.11 Fuse is an ultra-fast acting cylinder-type fuse specifically designed to provide ample protection against machines with the highest levels of current inrush. This fuse is classified as a Fast Acting Fuse as it is designed to provide instantaneous short-circuit protection and break the circuit within a fraction of a second.

Application Field:

3404.0047.11 Fuse is a compact cylindrical fuse used mainly in the power distribution system. It is used to protect organic- and semi-conductive loads, such as speed drives, motors, autotransformers, and PFC converters from current overload, short circuit, and power loss. It is also used to develop continuity and minimized current interruptions during power system disturbances.

It is also used to protect equipment and wiring from fire and damage to equipment and personnel. This type of fuse is mainly used when long shut-down times are not acceptable due to production continuity. Due to its high-speed acting characteristics, it is also used in the wind turbine systems for fault protection.

Working Principle:

The working principle of 3404.0047.11 Fuse is simple; an alloy strip is installed as an internal element within the sealed cylindrical body. The current passes through the fuse strip and when the current reaches a critical limit, the alloy strip melts and automatically breaks the circuit.

The fuse\'s response time to the electrical fault is very low, typically within the range of 5 to 15 milliseconds. To be more precise, it produces a total clearing time of around 10 milliseconds. The fuses of this type are designed to perform at a maximum voltage of 690 VAC and a maximum current of 68 Amps.

The 3404.0047.11 Fuse is also designed with an extensive range of electrically and mechanically interchangeable fuses to cover a wide range of applications, including residential commercial, and industrial. This type of fuse is designed to meet UL and IEC standards in order to provide maximum protection against short circuit and over-current conditions.

Conclusion

The 3404.0047.11 Fuse is a compact cylindrical fuse designed for maximum protection against over-current and short circuit conditions. It is mainly used in power distribution systems, to protect organic and semi-conductive loads, motors, autotransformers, PFC converters, and wind turbine systems. It is designed to perform at a maximum voltage of 690 VAC and a maximum current of 68 Amps. This fuse is designed to meet UL and IEC standards in order to provide appropriate protection.
